porated also adds greatly to its rigidity and facilitates use of the velocipede.

Another and further important object of ad- 10 vantage of the rear frame member of this invention resides in the provision of means for securing the device to a backbone.

Another and still further object of the improved rear frame member resides in the provi- 15 sion of means. whereby an end of a backbone may be secured to an axle positioned beneath the surface of the member. 7

A still further object of importance and advantage resides in the provision of means for 2 securing an axle against the lower surface of the member.

Additional objects of advantage and importance will become apparent as the following detailed description progresses reference being had 25 to the accompanying drawing wherein,

Fig. 1 is a top plan view of a rear frame member which embodies the preferred form of the invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

30 Fig. 3 is a transverse section taken on line 3-3 of Fig. 1.

Fig. 4 is a longitudinal section taken on line 2-2 of Fig. 1 and shows slightly modified form of the invention. 35 Fig. 5 is a transverse section taken on line 5-5 of Fig. 4.

As shown in the drawing: The reference numeral l indicates in general the body of the rear frame member of this 40 invention which in the preferred embodiment is constructed of a single sheet metal member. The edges l2 of the body It] are turned downwardly as is clearly shown in the drawing. The downwardly turned edge 12 at each end of the body 45 I0 is apertured I4 to receive an axle I6 as is best shown in Fig. 3.

Projecting upwardly from the upper surface of the body l0 closely adjacenteach end thereof is a securing lug I8. The lugs l8 are pref- 50 erably formed by turning upwardly portions of the body ll'i as is best shown in Figs. 2 and 4. The lugs l8 are to be spot welded or otherwise secure to a backbone 20.

Formed in the body H1 in alignment with and extending outwardly from the outermost surface of each lug I8 is an opening 22 which is adapted to receive the rear portion of a backbone.

In a slightly modified form of the invention as is best shown in Figs. 4 and the body 40 is 5 formed with downwardly projecting flanges 24 which are adapted to be crimped about an axle l6. The flanges 24 are formed by striking down the portions of the body In indicated by the reference numerals 25, 25.

The flanges 24 are adjacent the longitudinal center line of the body and may extend substantially the entire length of the frame.

It will be apparent from the foregoing that herein is provided a rear frame member for 1 velocipedes having the conventional bifurcated backbone.

It will be further apparent from the foregoing that herein is provided a device to which an axle may be secured without resorting to welding or other conventional securing methods.

Although but one modification from the preferred' embodiment of the invention has been herein shown and described it will be understood that many details of construction shown 25 may be altered or omitted without departing from the spirit of the invention as defined by the appended claims.

I claim as my invention: i

1. A rear frame member for velocipedes comprising a stamping having a relatively fiat upper surface, a backbone receiving opening near each end of said upper surface, said openings being in alignment and adapted to receive the rear end of a bifurcated backbone, and means formed of crimp-able portions of said stamping for positioning an axle beneath said upper surface.

2. A rear frame member for velocipedes comprising a stamping having a relatively flat upper surface, a backbone receiving opening near each end of said upper surface, said openings being adapted to receive the rear ends of a bifurcated backbone, and means for positioning an axle beneath said upper surface, said means including an integral part of the stamping adapted to be crimped about an axle.-

3. In a rear frame member for velocipedes comprising a stamping having an upwardly turned backbone securing member adjacent each end thereof, and downwardly turned flanges adapted to be crimped about an axle positioned against the lower surface of said stamping.
